Eleuterus or Eleutherius was pope from about 175 to 189 (the Vatican cites 171 or 177 to 185 or 193). He was born in Nicopolis in Epirus. The Liber Pontificalis claims that he corresponded with a British king, Lucius, who desired to be converted to Christianity. Historians, however, doubt the veracity of this tale; there appears to be little evidence supporting it.
